Download mp3 file from jsp page

The first step to downloading a file is to create an HTTP client object that would issue the request to the server. For this, we will be using the CloseableHttpClient class. The code snippet that creates a new HTTP client is as follows:. We then need to create an HttpGet or HttpPost object to send the request to the server.

The request is created by the following line of code:. The execute request function is applied to the client object and returns with a response from the server.

Once the request is sent to the server we need a response object to receive the data sent from the server. To catch the response from the server we use the HttpResponse class object.

The data sent by the server in the form of a message is obtained through the getEntity function. You can also obtain the response code sent by the server through the response object and use it to your specific need. The data to be downloaded is encapsulated within the entity object and can be extracted using the getContent function. The getContent function returns an InputStream object that can be further used with a BufferedInputStreamReader to enhance performance.

Now all you need to do is read from the stream byte by byte and write the contents into a file using the FileOutputStream class. The last thing required to be done is closing all the open resources in order to ensure that the system resources are not overutilized and that there are no memory leaks.

So there you have it - these are the simplest ways to download a file using the basic Java code and other third party libraries. Now that we are done with the basics, you can be as creative as you want and utilize the knowledge to suit your needs. So see you next time with a new set of concepts to help you become a better coder.

Let me know if I need to provide more information. I'm fine with trying out anything that's available- tutorials, links, books, hints,.. Paul Clapham. I like When you post, look below the box where you are typing and you'll see there are some checkboxes. If you don't, then the forum software will attempt to evaluate the HTML you entered rather than just echoing it. I edited your other posts and checked that box. Thanks, Paul. I'll keep that in mind.

Update: I'm going to be trying this tomorrow. Have found a couple of helpful links.. In this document I will guide you to upload and store files in the database, then download the data from the database. Upload data files stored in the column with data type is BLOB. Java Util Zip. File; import I want to take the files inside the folder. Can you help how it could be done.
